Fwd: SWAT-CUP Calibration

[Cihangir Arslan]

Hello there

I want to calibrate my SWAT model. Calibration years 01.01.2020 - 31.12.2020. Warm up period 3 years. I tried all the problems written in the groups but I could not find the error. I tried various alternatives but I could not solve it. It gets stuck after the 1st simulation. Calibration does not continue. I am attaching the documents related to the subject.

I would be very grateful if you can help me.

Your observed.txt and observed_rch.txt should start from 2015, not 2012, because you should exclude warm up period in observed files. So your first data point should be 2015-1.

Hello Mr. Huang and other group members

I made the correction as you said, but it's still stuck in the same place.

In addition, the parts I experimented with are as follows:

·        since the simulation was completed in 2020, I tried IDAL=366 in file.cio. I also tried IDAL=365 and IDAL=364 (364 worked in a previous model).

·        ‘In Sufi2_extract_rch_def’ and ‘extract_rch_No_Obs.def’ I tried 6 or 7 in the “variable column number(s) in the swat output file” section.

·        I made the warm_up period 2 years in the swat model and made updates accordingly

I have tried the above changes with various variations, but still no results.

If you can think of anything wrong or see anything wrong, I can correct it immediately. I would appreciate your help.

Hi there,

1. 2020 is leap year so keep it as 366, but you might want to check your climate data to see if your number of data points are consistent with the day numbers. 

2. Column 7 is the correct column so no need to change that. Your SUFI2_extract_rch.def is incorrect, because you didn't specify which subbasins you are extracting the outflow. It should be like this:

even you only have 1 observed station, you still need to extract it. So in your case, number of reaches to get for the first variable is 1, and reach numbers for the first variable is 25.

3. Just to make sure, in var_file_name.txt and var_file_rch.txt, remember to put the file name that you are going to extract, in your case: FLOW_OUT_25. This should be consistent with the name in observed files.

Hello, Mr. Huang,

I thank you very much for your help.

The problem is completely solved. It was the SUFI2_extract_rch.def file.

Thank you very much again for your precious time and help. :)

Best regards
